DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file transfer method and a file transfer apparatus for transferring a file subjected to read access (hereinafter abbreviated as "access") to another connected device, and a computer which records a file transfer program. In particular, the present invention relates to a file transfer method and a file transfer apparatus for selectively and automatically transferring an accessed file to another connected device, and a computer-readable recording medium on which a file transfer program is recorded.

[0002] Here, a file is a minimum unit of a resource handled by a resource providing side.

[0003]

2. Description of the Related Art Conventionally, there is a technique called "cache" for accessing a file provided by a server computer via a communication network at a high speed by a client computer. No. 4-313126.

[0004] The "cache" refers to a hard disk of a client computer or an alternative server provided between the client computer and a communication network (referred to as a gateway computer in the aforementioned publication).
When the next access request to the same file occurs in the client computer, the contents of these hard disks are accessed. This speeds up file access between the server computer and the client computer.

The above-mentioned "cache" function has been intended only to speed up the access processing to the same file from the next time. Therefore, these accessed files are not automatically transferred to various information devices directly connected to the client computer.
The transfer of this file has been performed manually by the user.

In this manual operation, the user determines for each of the accessed files whether it is a file to be transferred to any of the connected information devices, and performs a file transfer operation according to the determination result. Therefore, there was a problem that the file transfer operation was cumbersome and erroneous operation was easy.

Therefore, an object of the present invention is to provide a file transfer method and a file transfer apparatus capable of transferring and accessing a file accessed in response to a request generated inside the apparatus to a required one of a plurality of connected apparatuses. Another object of the present invention is to provide a computer-readable recording medium on which a file transfer program is recorded.

In this embodiment, the access request A
The computer 1 is a device that accesses the file FL according to the R and selectively transfers the accessed file FL to various connected devices based on the data type.
However, this device is not limited to the computer 1. For example, it may be a TV connected to a communication line such as the Internet.

According to the above-described embodiment, the file FL provided by the server 2 is a file obtained by converting the cooking time in a microwave, for example, into a file (the extension of the file is, for example, “. Cook”. If the file provided by the server 2 is accessed from the in-home computer 1, the file is automatically transmitted through the computer 1. The data is transferred to a microwave oven connected to the computer 1 based on the data type indicated by the cook, and the microwave oven can be operated according to the contents of the file FL for application such as home control.

Further, in this embodiment, a file conversion function by the file conversion processing F9 is provided. Therefore, even if the data type is the same, the file FL is connected to the computer 1 depending on the data format or content of the file FL. This is effective when the processing cannot be handled by a processing device or storage device.

For example, the computer 1 can use a GIF or JPEG file F1 as image data.
Since the digital camera cannot process the file F1 in the data format as it is, the file F1 can be processed by converting the content or format so that it can be processed in advance by the file conversion process F9. In addition, by using the storage device of the present embodiment as a device dedicated to backing up a file FL, it is possible to use the device in such a manner that only the file FL corresponding to the required data type of the accessed file FL is automatically backed up. is there.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
